I use a HooToo battery operated travel router. Works like a charm and pretty affordable on Amazon.

I had this on a cruise and it worked fine.

I've had this for a couple years now. I used it with the GearVR and Daydream headsets flawlessly. My video app of choice is Samsung VR because it supports travel mode. Should work with the Go as well.

I use one of these HooToo travel routers all the time.

I can charge my phone, share my usb disk and using hotel internet securely with my laptop and phone at the same time.
